22re piston ring end gap?

[orang-kr8]

Hey guys, Im rebuilding my motor out of the daily driver, (88 toyota pickup) The machine shop bored it .20 over.

I have a little over 1000 bucks into it now, so Im not ready to watch it blow up (again).

Piston ring end gap for the TOP RING in chiltons says .010in to .019in

My ring is at .011in with the feeler gauge, but with some effort I could fit .013

My machine shop guy says its way too tight, it will blow up. I dont know if I should believe him because he wants me to pay him to assemble it and he is an ass. I dont want to pull the pistons back out, Its almost completely assembled now.

General rule of thumb for ring end gap is .004" to .005" per inch of bore. Not knowing exactly which engine you have and what the bore size is I can't give you much more than that, also find another engine builder, if your not comfortable with your guy your gut is trying to tell you something.

I just did a quick google search and the the number that poped up was .018" but you should do a little more research

I was afraid of that, I guess I will have to pull it back apart then. My cylinder is just over 3 1/2 inches so I should need atleast .014in if not .018in or .020in. Thanks for the help, you saved me alot of money and time.

I also will not be using the same machine shop in the future, He constantly lied about parts of my motor being finished when they never moved off the floor where I left them two weeks earlier. I dont think I got screwed, but I never felt I could trust him. He also told me that a crankshaft that seized beyond being machinable would be fine with a quick polish. He said he would ''just run it''

WOW I hope you are checking his work I know I would be even if I had to take it to someone else to have it checked.
I know you don't trust him but you may want to go ahead and have him assemble it provided he gives a warranty when he does the assembly.
If you do it yourself and something goes wrong he won't be liable even if it was caused by his work since it will be really hard to prove and he
can argue that it was an assembly error.
